Here’s the intro from Doceri’s website:

Doceri™ is a revolutionary iPad software suite for classrooms, conference rooms, and auditoriums – any place where you give presentations, teach, or collaborate.

In a nutshell, Doceri is the ultimate tool for presentations and lessons. Through the Doceri Remote iPad app and Doceri Desktop software, you can control a computer (Mac or Windows), easily launch any document or application, and annotate over them at any time. You can save drawings and play them back in the future allowing even better presentations to be created from your existing PowerPoint or Keynote slideshows. If you just want to use it as a whiteboard, you can create any handwritten/drawn content on any background of your choice. And with additional room control hardware, Doceri can even be used as the remote control for projectors, DVD players, and all other audiovisual devices in your room.

Doceri is the presentation control that you’ve always wanted!

So here are some things that I’ve found less than ideal about Doceri (and let me be clear; these are minor in the grand scheme of things):

– the mouse functionality, especially beyond clicking, takes some getting used to: to click and hold, you have to tap with one finger and then tap another finger and then drag (for scrolling, say); this is a bit cumbersome, though I don’t find myself needing to do it too often (there are stylus issues here as well, in terms of both Doceri’s and third party stylus)

– Doceri advocates the use of the recording function (whatever you do in a given session is automatically recorded and then re-playable); this is a very cool feature but I’m not yet sure (because I’ve not researched it much yet) what can be done with those recordings outside of Doceri; they are saved with a proprietary extension that seems incompatible with other applications

– the clicking, because of the use / size of a fingertip or stylus, can be somewhat imprecise; you can zoom the screen in on the iPad but this is an extra step; again, not a deal breaker but it does take some getting used to

Let me also address here the stylus issue. Using a stylus makes it much easier to write. I have been using a generic Targus stylus, which works quite nicely. Doceri, however, sells their own stylus that works more like a pen/pencil, i.e. there is a writing end and an erasing end. I just got the Doceri stylus today and have only played around with it a bit, but here are some initial impressions:

– one of my iPads (I admit it; I have two: a 1 and a 2) has a screen protector on it; the Doceri stylus seems not to connect as well through the screen protector (having compared the usage both with and without the protector

– the Doceri stylus actually plugs into the headphone jack of the iPad (and apparently requires the volume to be up); this I assume increases its functionality, but the cord between the two can be an annoyance

– the Doceri stylus doesn’t feel as natural when writing, almost like a cheap ballpoint (feeling very scratchy and metallic); it also seems as if the Doceri stylus has to engage, i.e. it has to push down past a certain point to write; this is less the case with the unprotected screen but still an issue; in short, the Doceri stylus seems not to be able to keep up when writing quickly

– the Targus stylus has none of these problems but….

– the Doceri stylus has the added functionality of erasing with the stylus; this seems like a good thing but, with the stylus plugged in, the pen and eraser buttons disappear from the Doceri toolbar (which seems unnecessary); indeed, the stylus eraser is a cool thing but to flip it over might (might) make it a less efficient process than simply tapping the eraser button

– on the other hand, the Doceri stylus allows more seamless dragging / scrolling in that tapping with the stylus allows dragging without incorporating the second finger (necessary with the Targus stylus or finger-use)
